The library running on attiny85 very well? But i have to control power use, how to sleep the screen power and soft wake? chip avr/sleep? or use oled.on / off function?

Use oled.off() before you sleep the ATTiny85, and oled.on() afterwards.

The SSD1306 retains all its settings and display ram, and uses next to no power when it is off.

I've created a coin cell powered game, which sleeps waiting to be woken by the turn of a rotary encoder, and the power drain when asleep is so low I don't need a physical power switch.

Thanks. That was great with ssd1306.
